First, helmet equipment. The helmet is no longer just a protective tool, but a soldier's second brain. Install a miniature radio, a microphone and a pair of headphones in a very limited space, which is convenient for soldiers to contact their comrades-in-arms and commanders. The radar device on the upper part of the helmet will report the exact position of the soldier, and the molecular observer in front of the right eye can show the type of weapon. During the Iraq war, the US special forces and elite army infantry units were equipped with new light military helmets. Each helmet costs about $63. Compared with the traditional combat helmet, this helmet has many advantages. It is not only comfortable and reliable, but also has good communication skills. This helmet has better light shock resistance than any helmet used by the army and special forces. This helmet is the only impact helmet used by the special forces command to equip motorcycles and off-road vehicles. The higher brim provides users with a wider field of vision. With this helmet, fully armed users can still hit the target when they lie down. The shock-proof system of the helmet has some special components that can enhance the durability of the helmet. Second, shoulder equipment. Soldiers will carry a small computer and advanced multimedia system on their shoulders. At present, Motorola has developed a microcomputer. In order to use the computer more comfortably, a small mouse will be equipped on the belt of the military uniform. In this way, computers, communications and other technologies will become the most common weapons worn by soldiers on the waist, back, shoulders and head. These devices will directly connect soldiers with some of the most advanced command, control and communication systems equipped by the army. In addition, soldiers will be equipped with a backpack and wiring system, and other subsystems can be plugged into this system, including a radio station. Third, night vision equipment. At present, the most advanced night vision equipment equipped by the US Army is AN/PVS- 14 monocular night vision goggles. Night vision goggles have a resolution of 1.3 rpm/radian, weigh 0.4 kg, and are flexible to use. They can be worn on the head and observed with one eye, held by hand or mounted on a rifle. Soldiers can even take it off their helmets if they don't need it. It can also be used as a hand-held observation device, and can also be placed on the aiming rod of light weapons (such as M- 16/M-4 rifle) as a rifle aiming device. Besides being installed on M4A 1 carbine, it can also be installed on the special combat improvement of M4A 1 carbine, and used on M240 and M249B automatic weapons M 16A2 and M 16A4 rifles. Its unique waterproof design enables it to be used in water 20 meters deep. Night star binoculars can be used day and night, so that troops on the battlefield do not have the weight and volume burden of two sets of night vision goggles day and night. This kind of night vision goggles integrates the third generation image intensifier tube, eye safety laser rangefinder and digital compass into a hand-held light night vision device. These systems display the target distance on the eyepiece display, and have RS-232 data interface, which can transmit the distance, azimuth and pitch data to the combat computer, and the computer will provide the target distance to the fire control system. 4. M4/M4A 1 5.56mm carbine. The M4/M4A 1 type 5.56mm carbine can be said to be the most suitable light weapon for individual soldiers in the US military's active equipment. The biggest feature of this gun is its light weight and small size, and it has the firepower and accuracy of M 16 rifle. It can be used as both a submachine gun and a rifle. Its improved M4A 1 forms a modular weapon system, equipped with a variety of accessories suitable for individual use. The M4/M4A 1 5.56mm carbine is a lightweight and shortened gun derived from the M 16A2 rifle, which is basically the same as the M 16A2 rifle, and 85% of its parts can be interchanged with the M 16A2 rifle, thus greatly simplifying the training, maintenance and maintenance of weapons. The gun weighs 2.54 kilograms and has an effective range of 600 meters. Telescopic butt stock is adopted, which has strong firepower and high shooting accuracy. Equipped with a new type of competition sight, the wind direction deflection and shooting angle can be adjusted within 800 meters. 5.SR-47 assault rifle. SR-47 assault rifle is the product of the war in Afghanistan. At that time, in order to solve the problem of insufficient ammunition carried by American soldiers in tunnel warfare, American Knight Ordnance Company developed an assault rifle and AK-47 assault rifle that fired 7.62× 39mm Soviet-made bullets and magazines on the basis of M4/M4A 1 carbine. The purpose is to enable American soldiers to use the magazines of AK-47 rifles selected from the battlefield when they run out of bullets. Six, M82A 1 type 12.7mm anti-equipment rifle. At present, the large-caliber sniper rifles equipped by the US military are mainly M8A 1 model 12.7mm anti-equipment rifles. The gun became famous in the Gulf War of 1990 ~ 199 1, and it triggered a craze for countries all over the world to equip large-caliber sniper rifles. Therefore, M82A 1 anti-equipment rifle has become the reference standard of many anti-equipment rifles, which are mainly used to attack and kill the enemy's effective forces from a long distance. Total gun weight 12.9kg, magazine capacity 10 rounds. The barrel is a short recoil automatic pistol. After firing, the gunpowder gas pushes the projectile forward along the barrel, on the other hand, it acts on the bottom of the shell, and the thrust is transmitted to the bolt, then to the barrel connecting sleeve by the bolt locking projection, and finally to the rear of the bolt frame through the bolt body. Seven, benelli M4 Super 90 shotgun. In 2000, the American Army's "Three Services Combat Shotgun" was selected, and the M4 Super 90 Shotgun jointly developed by German HK Company and Italian benelli Company won the bid for its excellent performance, becoming the latest standard shotgun of the American Army. The U.S. Department of Defense ordered 25,000 pieces at a time and is still delivering them. It is reported that the US military used this gun in the battle to clean caves in Afghanistan. M4 Super 90 shotgun is mainly composed of M 1 and M3 Super 90 shotgun, except air guide, automatic loading mechanism and two pistons under the barrel. The gun also adds two sets of piston systems to reduce the recoil of the weapon. Eight, "Predator" short-range anti-armor weapon system. The weapon system has the characteristics of small size, light weight, compact structure, easy to carry by individual soldiers, low smoke, low recoil and low noise, and can effectively deal with close targets, so it is an ideal weapon for street fighting.

The guidance system is an optical aiming and inertial autopilot, which has the combat capability of "no matter after launch". It can be used to destroy current and future main battle tanks and targets such as bunkers and fortifications. Nine, sniper detection technology. At present, the United States has developed sniper detection technology which mainly adopts acoustic measurement, infrared and laser principles. This system has the following types: single soldier suspension, fixed installation and mobile platform carrying. The system is fixed, using two microphone arrays on both sides of the protected area or six unidirectional microphones distributed in the protected area. The microphone is connected with the command node through a cable or a radio frequency link. In order to locate accurately, it is necessary to determine the distance of the microphone in advance, and the accuracy should be within 1 meter. X. Partition detection technology. The technology of detecting people by partition wall can improve the situation awareness, reconnaissance and survival ability of urban combatants. At present, the United States has developed detection technology using electrostatic field, ultra-low frequency electromagnetic energy, radar vital signs monitoring and ultra-wideband radar principle. In the technology of detecting people by using electrostatic field principle, the "human body detector" developed by the United States works by using the principle that the human body can generate electrostatic field and there is attraction between two electrostatic fields with opposite polarities. When in use, the operator uses the "human detector" to scan around. When there is someone in front, the electrostatic field of the "human probe" and the electrostatic field of the human body generate attraction, which pulls the antenna of the "human probe" to the direction where the person is, so that the "human probe" faces the person and identifies the matching electrostatic field. The "human detector" can also be customized as needed to detect other living and inanimate targets. The prototype of the "human detector" has been developed, weighing 0.45 kg and powered by a 9-volt battery. It can be used for 3-4 days and can detect people behind the wall within a distance of120-140m. XI。 Micro UAV.
